My first thought when I read 'bitmaps' was Win32 bitmaps, after which I 
read this and it seems to be some sort of massive array of bits which 
can be manipulated? Oh wait, this is a wrapping of a number handled as 
an object /w metamethods, correct? If it is then this is a new take on 
the problem I hadn't considered at all! Nice to see a new take on the 
problem, but I'd be annoyed at using such an interface when I want to 
just do i = i << 1 and then use i for some other calculation.

Roberto said they (inner Lua dev group) weren't happy with any known 
implementation of bitwise operators, it would be helpful to know what 
they are not pleased with so we may propose alternate 
solutions/implementations.
